Holy Guacamole Batman!
So I was just getting out the fixins to make some chicken burritos. I grabbed the salsa container - an unopened 3lb container that I picked from the refrigerated deli section at Costco last week. The plastic container was totally bulged out. When I unscrewed the lid, the plastic seal bubbled up like an inch, and tight as a drum. I obviously wasn't going to eat it, but I figured I would poke a hole in the plastic to release the pressure so it wouldn't explode or something when it warmed up in the trash can.
I barely touched the tip of a knife to it and BAM! Holy hell - my ears are still ringing. The thing blew like a hand grenade and there were even salsa chunks on the ceiling in the kitchen. The container itself didn't burst, but when the plastic film did, it was like a gunshot. I'm actually lucky in that not all that much salsa shot out. It could have been a real mess, but for whatever reason, only maybe a few ounces shot out. Still made a mess though.
I'm really curious as to what caused the gas build up. It was in the 20s when I was at Costco, so it's not like it sat in a hot car on the drive home. I guess I'm lucky it did what it did, or I would have eaten it and maybe gotten food poisoning.
Anyway, who knew that salsa could be a destructive device?
Did I mention that my ears are still ringing?
